' 1 Claim.

This invention relates to a brush and particularly pertains to a handbrush of thefountain type in which the brush back of handle is hollowand forms a reservoir for a liquid soap.

Heretofore brushes of this character have been devised primarily withthe view of effecting delivery of a liquid soap directly to the bristlesof I the brush, and accordingly such devices usually involve a valvecontrolled discharge outlet or nozzle arranged to direct the soap on orinto bristle tufts carried by the brush back or handle.

An object of the present invention is to provide a fountain brush inwhich the point of discharge of' soap from a reservoir in the brush backor handle is located apart from the bristles and at a point such thatthe soap may be conveniently deposited in the palm of the hand, or onany other surface apart from the brush or the bristles thereof, so thatthe operator may observe the amount of soap delivered, thus enablingavoidance of waste of the soap as may be frequently occasioned where thesoap is delivered to the bristles since the volume of soap so deliveredis not readily apparent.

An advantage attained by positioning the point of discharge apart fromthe brush bristles is that the soap may be deposited directly upon thesurface on which it is to be used so that it will be subject to beingimmediately acted on by the tips of the bristles and without the delayincident to the fiow of the soap along the lengths of the bristles andthe infiltration of the soap throughout the base portions of the bristletufts where it is not needed as is occasioned where the soap isinitially delivered to the base of the bristle tufts.

A further object is to provide a control valve construction in afountain brush which is operable on manipulation of the brushin a mannerto actuate the valve by imparting an impact thereon to effect ejectionof a spurt of soap from a discharge orifice.

With the foregoing objects and advantages in view, together with suchother objects and advantages as may subsequently appear, the inventionis carried into way of example in the accompanying drawing, in which:

Fig. 1 is a perspective view of the brush;

Fig. 2 is a view in longitudinal section showing the brush as up-endedin a position occupied when effecting discharge of the liquid soap, and

I showing the control valve in its closed position;

Fig. 3 is a perspective View depicting the maneffect as illustrated by gly from the wall ner' of manipulating the brush in effecting dischargeof its liquid soap content;

Fig. 4 is an enlarged detail in section of the control valve structure,showing the valve in an open position.

Referring to the drawing more specifically 6 indicates generally ahollow brush back or handle which is here shown as conventional shapefor grasping in the hand or bythe fingers, and which is fitted with agroup of bristle tufts I in a usual manner.

one end of the hollow back 6 is formed with a filler opening 8 fittedwith a closure plug 9 here shown as screwed therein, and through whichopening a liquid soap Ill may be delivered to the reservoir ll formedinteriorly of the back 6.

In carrying out the invention the bristle supporting wall i2 of the back6 is formed adjacent an end margin thereof with a discharge orifice l3which leads from the reservoir II at an end thereof and opens contiguousto but spaced from adjacent bristle tufts I in an end row thereof withat least a portion of the orifice disposed in the area of the wall l2extending between the end margin thereof and the adjacent end row ofbristle tufts as shown'in Fig. 4.

Extending transversely of the orifice I3 is a bore 14 which opensthrough the adjacent end l5 of the back 6 and in which is mounted forlongitudinal reciprocal movement a piston I8 formed with a head ll whichis spaced outward- I5. A spring 18, here shown as wound around the outerportion of the piston I6, bears between the wall I5 and the head I1 andacts to normally maintain the piston E6 .in an outermost position with aport IS in the piston disposed out of register with the orifice l3 andin the end wall 15.

The head I1 is fitted with a curved stem 20 which projects inwardly andoutwardly from the head and extends into a slot 2| formed by a bracket22 carried on the end wall l5, which stem and slot construction servesto hold the piston against turning and also limits outward movementthereof under the urge of the spring l8.

The bore I4 is of sufficient length to afford a space between its innerend and the inner end of the piston and provide clearance so that thepiston may be advanced to position the port l9 therein in register withthe orifice 13.

Leading from the inner end of the bore [4 to the reservoir II is anaperture 23 through which fiuid may pass from the bore [4 into thereservoir H on inward movement of the piston and may fiow from thereservoir into the bore on outward movement of the piston.

In the operation of the invention the brush back is grasped in one handand upended to position the pLu'np head I! downward as shown in of thehand, or against any other surface as illustrated in Fig. 3 so as toadvance the piston l6 upwardly in the bore l4 and thereby bring the portI 9 into register with the orifice l3 as shown in Fig. 4 so that liquidwill flow to discharge through the port l9 and orifice-l3, the liquidthus being directed outwardly and downwardly as indicated by the arrowsin Fig. 4 clear of the bristle tufts l and thereby beapplied directly tothe palm of the hand or to whatever surface as may be arranged beneaththe orifice l3. 1

Upward movement of the piston l6 forces liquid from the bore l4 throughthe aperture 23 into the reservoir. On release of the pump head frominward pressure thereon, the spring I8 will expand and retract thepiston so as to close the orifice I3.

By the construction and arrangement shown, the operation of the pumppiston above described may be rapidly effected so that the liquid willbe discharged from the reservoir through the orifice l3 in a shortspurt, and on effecting a series of quick successive operations of thepump piston a like series of spurts of the liquid will be formed. Sincethe discharge of the liquid soap may thus be readily observed, theoperator is able to determine the volume of the liquid soap delivered toa surface and accordingly may avoid excessive use or waste of the soap.

I claim:

A dispenser embodying a hollow elongated member having a longitudinalwall and an end wall; a reciprocal piston extending through said endwall and into said longitudinal wall and formed with a port extendingthrough a portion thereof housed in said longitudinal wall, saidlongitudinal wall being formed with a piston receiving borelongitudinally thereof and having an opening between the inner end ofsaid bore and the hollow interior of the elongated member, also adischarge orifice across which said piston extends, spring means fornormally holding said piston in a position with said port out ofregister with said orifice in the direction of the length of saidpiston, and a head on said piston arranged in outward spaced relation tosaid end wall adapted to be depressed to advance said pistonlongitudinally in opposition to said spring means to a position toregister the port therein with the orifice in said longitudinal wall.
